Embodiment Construction

[0019] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Control attached figure 1 and attached figure 2 , the present invention is a novel integrated PAC based on ARM and Linux integrated PLC function, touch screen, SQLite database, ModBus communication and other functions, the hardware includes processor unit, display touch screen unit, input unit, output unit, storage unit, communication Unit, the software includes Linux operating system, PAC operating system, Qt interface, SQLite database, communication, etc.

[0021] The PAC operating system is the core of the PAC, which completes input processing, program execution, output processing, communication, database, etc., and realizes the control function of the system. This compiled PAC pre-compiles instructions into ARM executable codes, which reduces the process of searching for instructions and has high execution efficiency. Co...

Abstract

The invention relates to a programmable automation control (PAC), in particular to a novel integrated advanced RISC machine-Linux (ARM-Linux)-based compiled PAC integrating the functions of a programmable logic controller (PLC), a touch screen, a database SQLite, ModBus communication and the like. Hardware comprises a processor unit, a display touch screen unit, an input unit, an output unit, a storage unit and a communication unit, and software comprises a Linux operating system, a PAC running system, a Qt interface, the database SQLite, communication and the like. The communication unit comprises an RJ45 network interface and a field bus ModBus, and has high extensibility. The running of a touch monitoring interface and the running of the PLC can be independent from each other, the hybrid programming of a ladder diagram, an instruction list and a C language is supported, and a hybrid program of the ladder diagram, the instruction list and the C language can be directly compiled into an ARM-executable file, so that the running speed of the compiled PAC is increased by 5 to 10 times compared with that of an interpreted PLC. The development efficiency and cost of the compiled PAC are more competitive than those of the conventional development mode integrating the PLC, a human machine interface and configuration software, and a broad application space can be provided for a user.

Description

technical field [0001] The present invention relates to a programmable automation controller (Programmable Automation Control, PAC), in particular to a new integrated compiling PAC based on ARM and Linux with integrated PLC functions, touch screen, SQLite database, ModBus communication and other functions. Background technique [0002] HMI (Human Machine Interface, also known as user interface), is a medium for interaction and information exchange between the system and users, and can be connected to programmable logic controllers (PLC), inverters, DC speed controllers, instruments and other industrial Control equipment is a digital device that uses the display screen to write working parameters or input operation commands through the input unit (such as touch screen, keyboard, mouse, etc.) to realize the information interaction between human and machine. [0003] Programmable logic controller PLC (Programmable Logic Controller) is an electronic system for digital operations...
